Pig-nosed turtles are an enigmatic group of reptiles with an extensive fossil record across the globe. The group is known to have inhabited North America during the Eocene, about 55 to 40 million years ago, but information is still limited regarding the exact morphology of these turtles, as remains are few. Here we document the morphology of the only known skull of a North American pig-nosed turtle based on a fossil from the middle Eocene Washakie Formation of Sweetwater County, Wyoming, USA.

Duboisia santeng is an extinct Indonesian antelope with short horn cores that sprout up like bunny-ears. A newly discovered skull of Duboisia from north-eastern Thailand confirms that the genus is no longer endemic to Indonesia, and supports a strong faunal interchange between the South East Asian continent and islands before or at the beginning of the Pleistocene.

A new species of fossil mite, Immensmaris chewbaccei, is described from the 100 million-year-old (Cretcaeous) Burmese amber of Myanmar. It belongs to the modern family Smarididae and is of particular note for its enormous size, with a body length of about a centimetre. This makes it the largest example of an erythraeoid mite (the wider group to which it belongs), and in general it is one of the biggest mites ever to be recorded.

We give closure on the study cycle of turtle material from Vic area, Middle–Late Eocene, Ebro Basin, Catalonia, Spain. Numerous comparisons with poorly known taxa are carried out, including a first description of the Eochelone shell via E. voltragana. Different swimming evolutionary states and different cheloniid subgroups Osonachelus and Eochelone are described, as well as dispersion Gondwanan forms from Africa and around European coasts.
